Adaptive modulation communication system

摘要

In an adaptive modulation communication system that adaptively varies a modulation scheme for each transmit unit, a transmitting-side apparatus sets different error detecting units corresponding to bit position, and transmits data subjected to error detecting processing on a different error detecting unit basis corresponding to bit position, and a receiving-side apparatus performs demodulation independently for each of the error correcting units using different demodulation patterns to obtain received data.
